To answer my own question I'm gonna have to go with Suicune as my favorite legendary looks wise. Normally I'd go with something along the lines of Lugia or Giratina due to how quickly they can grab your attention with sheer bulk alone but what I like about Suicune is that I feel like it doesn't need to be overly massive or frightening to be awe worthy in all honesty, it just screams sophistication and class imo and that's what I like about it lol.
